Carter Bays, co-creator of “How I Met Your Mother,” took to Twitter to respond to criticism about a recent episode of the hit CBS series which features the show’s stars dressed to appear Asian.

In an episode titled “Slapsgiving 3: Slappointment in Slapmarra,” members of the cast are in what is being described as “yellowface.” Since airing, the episode has spawned the hashtag #howimetyourracism and garnered criticism across the web.

Tara Aquino wrote on Complex.com about the episode,”the dismal portrayals of Asian people and cultures we do get, and lack of Asian representation on screen, directly influences how audiences view Asians, what they expect from them, and how they treat them.

In response to the criticism, a series of tweets were posted on Bays’s Twitter account:
